One of the main differences between a propeller pump and a centrifugal pump is the absence of a __________.
β’ Centrifugal pump internal flow path and casing design β’ Propeller (axial-flow) pump characteristics and when they are used β’ Role of a volute and how it affects fluid velocity and pressure
β’ Think about how a centrifugal pump changes high-velocity water into pressure β what part of the casing helps do that? β’ Consider how water moves through a propeller/axial-flow pump. Is the flow mainly radial or straight through? What does that suggest about the casing shape? β’ Ask yourself which component is closely associated with radial flow and swirling discharge versus straight-through axial flow.
β’ Identify which pump type normally has a volute-shaped casing around the impeller. β’ Decide whether a propeller pump usually needs a volute, or if it uses a simpler, straight-through casing or tube. β’ Confirm that a centrifugal pumpβs main difference here is about its casing shape, not pistons or nozzles.
